Error Detection And Correction
1. Error Detection
and Correction Basic conceptsBasic concepts
Networks must be able to transfer data from one
device to another with complete accuracy.
Data can be corrupted during transmission.
For reliable communication, errors must be
detected and corrected.
Error detection and correction are
implemented either at the data link layer or the
transport layer of the OSI model.
6. The term burst errorburst error means that two or more
bits in the data unit have changed from 1 to 0
or from 0 to 1.
7. Error detectionError detection
Error detection means to decide whether the received
data is correct or not without having a copy of the
original message.
Error detection uses the concept of redundancy,
which means adding extra bits for detecting errors
at the destination.
